Calcium channel blockers can cause swelling in your limbs. If this happens for you, it probably won't get better over time, so talk to your doctor about alternatives if it bothers you.

Women are more likely to have side effects (especially swelling) from Verapamil than men.

You can't miss doses. Stopping Verapamil suddenly can cause your blood pressure to go up suddenly, which raises the risk of heart attack and stroke.

Not a good medication for you if you drink alcohol.

How it works

Verapamil is a calcium channel blocker. It lowers blood pressure by slowing your heart rate and relaxing your blood vessels. Your heart gets more oxygen and doesn't have to work as hard to pump, which can relieve chest pain.
